What is myeloma?

Myeloma is a cancer of the plasma cells. It happens most often in adults over the age of 50. Plasma cells are found in the bone marrow and produce antibodies (immunoglobulins) that protect you against disease. Myeloma is when the bone marrow has a type of immunoglobulin that reproduces uncontrollably. Myeloma cells can disrupt normal blood production and the functioning of the immune system, damage the kidneys, and form into masses.
